We consider how best to understand the origins of the laws and customs of the Jewish people, or what we call "Judaism." We begin by dispelling the notion that Judaism (or any other belief system apart from Christianity) can properly be called a "religion" -- a category that derives originally from Christian practice and does not make sense anywhere else. We further examine the roots of the idea of "Judaism" as a concept for the Jewish way of life, concluding with a careful analysis of the meaning of the ancient Greek word "ioudaismos," which originates in the Book of Maccabees. Finally, we trace the best possible explanation for the origins of the Jewish people in the Bronze-Age Near East, using archaeological evidence including an ancient Egyptian monument and the vandalized ruins of Canaanite temples. Ultimately, we should be able to understand Judaism and its God as the creations of a particular Middle Eastern people not entirely unlike their ancient neighbors.
